Class AbstractTextureCache

java.lang.Object
  org.j3d.renderer.aviatrix3d.texture.AbstractTextureCache

All Implemented Interfaces:

AVTextureCache, org.j3d.texture.TextureCache

public abstract class AbstractTextureCache
extends java.lang.Object
implements AVTextureCache

An abstract implementation of the cache with a collection of useful utility methods for any cache implementation.

This class does not provide the storage structures for caching as each implementation will have different requirements. It just provides utility methods that most implementations will find useful.

AbstractTextureCache

protected AbstractTextureCache()

Construct a new instance of the empty cache. Empty implementation, does nothing.

Method Detail

load2DImage

protected TextureComponent2D load2DImage(java.lang.String filename)
                                  throws java.io.IOException

Load the image component from the given filename. All images are loaded by-reference. This does not automatically register the component with the internal datastructures. That is the responsibility of the caller.

Parameters:

filename - The name of the file to be loaded

Returns:

An TextureComponent instance with byRef true and yUp false

Throws:

java.io.IOException - Some error reading the file

load2DImage

protected TextureComponent2D load2DImage(java.net.URL url)
                                  throws java.io.IOException

Load the image component from the given url. All images are loaded by-reference. This does not automatically register the component with the internal datastructures. That is the responsibility of the caller.

Parameters:

url - The URL of the file to be loaded

Returns:

An TextureComponent instance with byRef true and yUp false

Throws:

java.io.IOException - Some error reading the URL
